UNITED STATES PATENT EEIGEo MICHAEL A. LYNCH, OF BOSTON, MASSACHUSETTS.

IMPROVEMENT IN LAMP-LIGHTING APPARATUS.

Specification forming part of Letters Patent No. 139,255, dated May 27,1873 application filed March 6, 1873.

`To ali whom it may concern:

- for Lamps 5 and do hereby declare the same to be fully described inthe following specilication and represented in the accompanying drawing,of which- Figures 1 and 2 denote transverse sections, and Fig. 3 ahorizontal section of a lamp-burner providedv with my invention, itbeing of the kind termed the Sun-Burner, as invented by Michael H.Collins. Fig. 4 is a top View of the cranked shaft, and Fig. 5 is an endviewof it and its tooth. Fig. 6 isa vertical section of the said toothand the fuse-tube.

M v invention, though somewhat analogous to that described in the UnitedStates patent No. 126,640, granted May 14, 1872, to the assignees ofWilliam A. Leonard, differs materially therefrom. I have no pointedfuseretainer applied to the fuse-tube. I do not operate the fuseelevator and discharger by means of a single lever. In the place of thelever I employ a rotary shaft provided with a tooth, a bell-crank, and aconnecting-link, all of which I arrange and combine with the fuse-tubeand the discharger, in manner as During each revolution of the shaft thetooth will be caused to raise the fuse a short distance, and thedischarger will be moved against the .protruding part of the fuse so asto ignite it by friction, the whole being certain and simple inoperation and not liable to get out of order.

In the drawing, A denotes the burner, of which a is the wick-tube and bthe wick-elevator. On that side of the wick-tube, which is opposite tothat to which the wick-elevator is applied, there is fixed to thewick-tube, vertically and at its middle, the fuse carrier or tube c, towhich the discharger d, in the form of a lever, as shown, is pivoted.The discharger placed alongside of the fuse-tube, as

represented, turns on a pivot, e', projected therefrom. At its footthelever-discharger is jointed to a short link or connecting-rod, e,extended from or pivoted to the bell-crank f of a shaft, g, such shaftbeing arranged with respect to the fuse-tube and the base It of theburner, in manner as represented. At its inner end the shaft carries asmall tooth, i, which, during each entire revolution of the shaft, willbe carried into and out of an opening, Ic, in the fuse-tube. On theouter end of the shaft is a milled head or button, l.

On taking hold of the button and revolving it the shaft will berevolved, whereby the tooth' will be made to act on the fuse of thefusetube so as to raise it in the tube, and the. striker or dischargerwill be moved against and across ,the upper to e`ect its ignition. Thefuse used is to be supposed to be a band of pyroxiline, or some ysubstance easily fusible, and provided on one side with a strip or layerof match-composition, easily fired by friction. The fuse so made is tobe inserted lengthwise in the fusetube, and should lit closely thereto,as a wick does in a wick-tube. When it may be desirable to inflame thewick of the lamp it will only be necessary to revolve the shaft, wherebythe fuse will be raised and fired so as to set fire to the wick. v y

I make no claim to the subject of the aforesaid patent.

I claim- A l y The shaft g, its tooth i, and crank f, the connectinglink e and the lever or discharger d, constructed and arranged togetherand with the fuse-tube c, substantially as and to operate as described,such fuse-tube and shaft being applied to a lamp-burner, as represented.
